HOUSTON – Expro has introduced the Galea autonomous well intervention system.
This is designed as a replacement for larger, more labor-intensive wireline rig-ups for slickline operations such as solids removal, plug setting/pulling and logging surveys.
The system can be configured in various operating modes for offshore and onshore applications.
In fully autonomous mode, Galea deploys a tool string into the well at regular intervals or as determined by the well conditions. Continuous remote monitoring is feasible from anywhere in the world, Expro adds.
When the system is in semi-autonomous mode, it performs a pre-programmed intervention sequence that can be initiated either locally or remotely.
This is said to be of benefit to multi-well platforms or pads where regular interventions are needed, such as paraffin wax scraping operations. A small intervention package permanently located at the well site is said to eliminate the need for a wireline unit.
Various fail-safe features are said to ensure containment and eliminate potential wire-breaks during interventions.
Finally, in manual mode the system is said to provide faster rig-up intervention, and when not in use, occupying a much smaller space at the well site or on deck than would be required for a standard slickline winch unit and PCE package.
